It is correct that there is no S/E taxi procedure at AWAC. But the company has done a lot of research into this and found that there is virtually no savings. I would probably concur based on anecdotal evidence.
The other day in LGA we had a very long taxi. While sitting basically stationary I shut down one engine. Every time the line crept forward I moved too. It took an awful lot of thrust just to break away from the spot and I had to maintain that higher thrust to keep moving.
When I restarted the left engine, it took virtually no thrust lever advancement to get the airplane moving.
There are likely times when a S/E taxi would help. But our company is not dumb and has actually researched this particular issue and found the savings to be minute, if they exist at all.
One big saver we do is to maintain flex thrust to 10000 feet out of most airports. Another is that we don't use reverse thrust on most runways. We crack the reversers, but don't pull them all the way. Of course, on short runways we use them and whenever the crew feels it prudent. But landing on one of the long runways in CLT there's no need. And it saves fuel and wear and tear on the motors.
The company does consider these things. Additionally, APU usage is being tracked in an attempt to save fuel.
But back to the original theme, there is no doubt that the savings would be far greater if they didn't run dumb flights.
The other day during a regular day we had 13 from SDF-LGA and then 23 from LGA-RDU. On a normal day. With at least one LGA-RDU flight later in the day.
If they really want to save gas, they need to re-think their route structures and some frequency of routes may have to go.
